Trying a different approach to blocking out the scene. Not only are 3D models very useful for pose reference, but with Blender's Eevee renderer I can also test out various lighting setups in real time, and use Cycles to get more realistic shading overall!
Although, looking at the time spent on posing, I coulda gotten multiple sketches done! xD
I certainly won't use 3D for everything, since sometimes it's easier to just pick up a pen and draw.
